TL;DR: In this paper, permanent magnet (PM) brushless direct current (BLDC) motors are widely used in industrial application such as electric vehicles, robot, and home appliances because the PM BLDC motors have potential to be small size due to their high energy density, performance and efficiency.

TL;DR: In this article, the authors analyzed the output characteristics of a high-temperature superconductor (HTS) coil depending on the turn-to-turn contact resistance and found that as the contact resistance decreases, the electrical stability increases but the output efficiency decreases compared with the input.

TL;DR: A simplified d–q equivalent circuit model of a permanent magnet synchronous motor with an ITF is proposed, developed by reflecting representative phenomena related to the negative sequence components of the fault in advance of a final model construction, such that the final model does not require the separation of positive andnegative sequence components.

TL;DR: A novel algorithm is developed along with the new experimental scheme and the FTCS can deal with the failure of up to two Hall-effect sensors and the method can be implemented with ease, is fast and does not require high end processors.

TL;DR: In this paper, a stochastic response methodology (SRSM) was introduced to find the tolerance band of design variables and estimate the characteristic distribution of the products, and the validity of this method was confirmed by obtaining statistically significant results for torque characteristics of the motor.
